First Public Running Day of 2014

The weather was fine and hot yesterday for our first Public Running Day of 2014 and the people came out for a ride on our trains in the hundreds. Thankyou.   A very pleasant sight was the number of families with blankets out on the grass enjoying themselves with a picnic lunch. We haven’t seen this sort of thing in a few years now due to the infestation of the park by thousands of Flying Foxes. For this we want to say a big thankyou to our patrons for your continued support during these last 5 or 6 years as we have struggled to survive due to the flying foxes keeping large numbers of the public away.   For those of you who want to know when the Toowoomba Regional Council will remove these creatures as promised by them last year, the answer is……….soon. … They informed us recently that as soon as the breeding season is over (February – March) and the new young are able to fend for themselves they will move in to have them all relocated. We cannot say any more than that, but to say that we are hopeful that is will be soon.   When it happens, we will be having a celebration to welcome in a new era for the Toowoomba Live Steamers Inc club. We have exciting things planned for this year and the public will be the benefactors. I cannot say what is happening shortly but it is exciting, so keep watching the web site or on Facebook because when it happens we will be letting you know.

Don’t forget, we are always looking for members so if you are interested in learning to drive a miniature steam locomotive, just contact us. Women can join and drive too as our Bec found out. Don’t be afraid, just do it.

The Koppel

We had the pleasure of having Koppel with us for a few weeks.

5″ gauge Rolling Chassis

Where possible I have re-cycled! The buffers were machined from plough shear bolts, pipe reducing unions, square washers and rewound bedsprings. The towing hook is part of a turnbuckle with a nut machined as a collar on the front.

The boiler feed axle pump was machined entirely from old brass plumbing and stock trough fittings. The stainless balls for the pump valves came from a ss ball race. It can push over 400psi off the dial of my test gauge! The axles are recycled bright round bar courtesy of the local tip, and the slip eccentrics were machined from a couple of 50mm tow-balls.

The smokebox was fabricated and welded from scrap steels, with the massive brass fittings on the stack coming from some huge phosphor bronze bushes from a friends junk-box. The handrails on the cab started life originally as flower pot hangers, but a few threads and bends changed that.

The crosshead slides are 3/8″ keys, with the crossheads fabricated from 11mm key and 3mm sheet steel silver-soldered together. They slide up and down just fine.

The majority of things are held together with 4mm bolts and nuts, cheap and readily available. So far everything has been done with only a Taig micro lathe, a drill press, portable drill, bench grinder, disc grinder, inverter welder, belt sander, and hand tools.

I have access to milling machines and large lathes at a friends around the corner, but much prefer the satisfaction of overcoming challenges and doing it myself. Quartering the wheels was an experience, but they measure up spot-on. The only major stuff-up to date was when I was drilling the holes in the wheels for the crank pins. The jig slipped or vibrated loose and I ended up with one wheel out by 0.5mm.

Took a while to figure out why the wheels were binding, then tracking down which crankpin was out of kilter took a lot of thinking carefully. The solution – I machined a new crank-pin for that wheel with a 0.5mm offset, keyed it and fixed it to the wheel. Works perfectly now with no binding of the gear.

Machining cast-iron wheels

The wheels were a real challenge on a micro lathe. Fortunately Taig supply a riser block set so that you can raise the height of the headstock and center and extra 40mm. This gave just enough clearance to spin the rough castings.
